Parade-of-Horrors Objection Law and Legal Definition

Parade of horrors objection refers to an argument that relaxation of a constitutionally imposed restraint under specific circumstances may justify further relaxation in broader circumstances. Relaxation of a constitutionally imposed restraint acts as an invitation to justify some other or further relaxation of that restraint. This is usually raised in the context of legalized human euthanasia.

Parade-of-horrors objection is also known as slippery slope principle or wedge principle.
